Synthesis and Evaluation of Ceramic‐Anchored Cu‐Ce‐MnOx Catalyst for Low Temperature Reduction of Diesel Engine NOx Emissions Using Liquefied Petroleum Gas or Adblue as Reductants

open access: yesEnergy Science &Engineering, EarlyView.
LPG converting harmful NO represented by the dark smoke to harmless N2 and H2O shown by the white smoke over Cu‐Ce‐MnOx catalyst. ABSTRACT Manganese oxide‐based catalyst doped with copper and cerium was synthesized through microwave irradiation and successfully anchored on a ceramic support.

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

open access: yesEnergy Science &Engineering, EarlyView.
This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

open access: yesEnergy Science &Engineering, EarlyView.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Synthesis of Tris(Dimethylamino)Phosphine‐Based InP Quantum Dots and Their Application in Light‐Emitting Diodes: Progress and Perspectives

open access: yesExploration, EarlyView.
A lot of subtle but key tricks in the synthesis of (DMA)3P‐based InP QDs and device mechanisms were not explicitly explained in the published works. This review firstly provides a comprehensive analysis of the molecular structures and distinct reaction mechanisms of (TMS)3P and (DMA)3P during InP core nucleation.
